Renowned Consul's Lieutenant leaves battlefield in response to his attack-trigger. Will other attacking creatures get +1/+1? Can we use LKI in this case?

Yep, you still get the bonus. Since the Lieutenant is not on the battlefield when the trigger goes to resolve, we look at how it looked when it was last on the battlefield. It was renowed, so your other attacking creatures will still get +1/+1.
